For fairness I have to point out that WAAF personnel did do significant radio and RDF work. This places a female voice in the frame for the ground controller (and the airfield section of the script).
As a pilot in distress (RAF or USAAF) you could get a WAAF on the emergency channel and she would do her best to guide you to an appropriate friendly airfield. If you weren't going to make it they'd put a rescue launch onto your last known position. In some instances Ground Controlled Interception units were staffed entirely by women, from the radar operators, through plotters, to controllers.

To undertake the WAAF controller role, a native British accent would be essential.

This has the potential to be a tricky one. I'm fairly sure that historically the met. service used nautical measurement conventions, and shipping for most of their data collection, but by the start of the Second World War the collection of meteorological data was a joint endeavour between the met., the Admiralty and the RAF.
Below is an account of a lady who worked as a met. Assitant, reporting to bomber command. Though her testimony is quite dry in places she gives the structure of the organisation quite succinctly.

I believe that all branches involved in collecting data worked in neutical measurements for collection / collation, but that these were then rendered to service-specific requirements.

I would have expected the RAF to use miles because their charts and air-speed indicators were scaled / calibrated in miles.

Things are substantially as Luke describes:
For communication within a squadron, pilots identified themselves by section, followed by the position within their section:
The primary section was usually Red Section (with the sortie's commanding officer leading Red Section), followed sequentially by Blue Section, Yellow Section and (if operating in vics) Green Section. By sections, pilots were positioned as “leader”, “two”, “three” etc.
"This is Gannic Leader. Red and Yellow Section follow me, Blue section stay high."
"Blue Leader Speaking, Bandits Up-Sun, Angels-Two-Zero... Prepare to Break to Port on my Command!"
These designations were positional and not specific to either a particular aircraft or pilot. They were allocated on a sortie by sortie basis at the discretion of the senior officer flying. One day you could be flying Spitfire B for Beer as your CO's wingman, call sign: Red Two, and another day you could be Blue Leader flying D for Dog.
Bomber Command (and units operating heavy/ heavier aircraft) may have employed different methods of identification, linking crews to specific aircraft, hence an aircraft ID letter based call sign. This would contrast with the fluid allocation of call signs employed within fighter / strike and tactical reconnaissance squadrons.
For communication outside the squadron pilots would be required to required to identify themselves by their squadron's call sign. IIRC Pierre Clostermann (Big Show) made frequent reference to this practice, as did Jeffrey Wellum (in First Light). They respectively state their squadron call signs were FILMSTAR and GANNIC (72Sqn).
Wikipedia has a listing of Squadron call Signs for the Battle of Britain, but I'm quite sure these were changed periodically to obscure the pattern of squadron deployments and are unlikely to have endured through to 1944/45: https://en.wikipedia.org/wiki/List_of_Battle_of_Britain_squadrons
On this subject I wonder if they are listed in “2nd Tactical Air Force - Volume Four” (Shores and Thomas), but I don't have a copy of Volume Four myself. Perhaps there is someone out there with a copy to hand, possibly willing and able to loan it for the duration?
Wing Commander Johnnie Johnson recalled being chided by his Intelligence Officer for failing to change his call sign “Greycap”. It was believed to be well known to German Signals Intelligence.
On RAF R/T usage see: “Forget-Me-Nots for Fighters”, 13 Group, 1940.
This collection of everyday pilot's wisdom was presented mostly in the form of humorous cartoon style illustrations. The Imperial War Museum's copy bears the hand written inscription “Pilot's Mess. Not to be removed” and “Please sign last page when marked – learned and inwardly digested. S.L.” Their example bears 20 signatures of 13 Group servicemen, dated 1942.
“Reporting of enemy
DON'T get excited, and DON'T shout. Speak slowly into the microphone. Report ALL aircraft, not one group, then a few minutes afterwards another one below or above.
* * *
If you see a formation of enemy aircraft look all round it, and report its escorts at the same time, using the clock system, and giving their height above or below you.
* * *
It is also quite a good idea when you have finished to put your R/T set on to receive.”
“R/T
Remember that “Silence is Golden.”
* * *
Maintain R/T silence unless you have some-thing important to say. Always say who you are; speak slowly – if it is really important speak slower than usual. This is quicker than having to repeat.”
“Use hand signals if you can. Remember that the Leader will tap his microphone if he thinks you have left your transmitter on. If you are guilty you had better avoid him when get home.”
“Don'ts”
“NEVER forget that the HUN is listening to nearly everything you say either on R/T or in the “Local.”
Be careful what you say on the former, and always resist the temptation of describing even you most successful patrol at the latter. It would be very hard to do so without telling HITLER something that he would like to know.”
“2nd Tactical Air Force: Volume Three, From the Rhine to Victory, January to May 1945” (Shores and Thomas, 2006):
“Operational Control
With the formation of 83 and 84 Groups came the requirement to provide operational control of the aircraft under their direction in the battle area. This was accomplished by the formation of a corresponding Group Control Centre (GCC) for each Group, much like the familiar Fighter Command Sector Operations Centres. In the GCC operations room the positions and directions of aircraft or formations within the area of operations were marked on a large horizontal map table, with plaques detailing numbers, height, and identification of each 'track'. The GCCs were fed by information from mobile radar units via landline or W/T links and communicated with the aircraft under their control by R/T (radio-telephone); callsigns for 483 and 484 GCCs (as they were formally numbered) were 'Kenway' and 'Longbow' respectively. Officers responsible for the planning and tasking of operations to be carried out by the Airfields (later Wings) within the Group were accommodated in cabins alongside the operations room. A large number of mobile signal units provided the R/T, W/T and telephone communications to facilitate the above organisation and the numerous links required to the Wings and other units under the control of the Group."

Excellent work! Thankyou so much for the fixes and additional content, especially the RAF pilot . I've been looking forward to meeting him since I first heard about the work in progress.
It's time to go screenie mad!

I've flagged it on the Russian site tonight, but I wouldn't expect a fix before monday.
As I've said before, I get the impression that the server is maintained during regular office hours only.
Anything sooner will be a bonus.
***UPDATE***
As of now (Saturday afternoon) both the server and the stats site appear to be functioning normally.
Bloody good job -DED- crew! Many thanks if you're reading this

Server stats can usually be found at: http://72ag-ded.ru:8080/en/ and are available in English, German and Russian.
Unfortunately they have been offline since publish 3.007 last week.
I have just flagged this up on the Russian language forum, so if they hadn't noticed, they will now

My comment was (admittedly rather vaguely) addressed to the poster who described the frayed edge as looking hand painted. Perhaps I should have made that clearer.
I don't doubt you know your subject matter - I have PM'ed you before to congratulate you on your work.
I included your picture as an excellent example of a real hand painted roundel.

Please consider this observational rather than critical:
Many hand-painted roundels appear as in the picture above, showing colour bands described with concentric brush strokes.
Because of the low opacity of the paint I would expect to see the a deeper and more opaque line wherever paint was built up towards an edge:
This is especially prominent in the outer edge of the outer colour band between 3 and 7 o'clock and there also appears to be evidence of a drip beginning to form in the now-cured paint at the very lowest point.
What I believe my co-posters are referencing is a sharp-edged effect which is not consistent with applying a greasy paint or emulsion to doped linen.
For those unfamiliar with doped linen, the surface finish is very very smooth indeed and once treated does not have an obvious textile grain. To all intents and purposes it holds a shine just like sealed wood or sheet metal.
This is the type of edge texturing you'd expect if the RAF pilot had hand painted the roundel directly onto his knitted jumper.

When the server was down yesterday I called it in on the Russian forum and -DED-ASF had it back up within an hour. I was concious to get the request in as early a possible (GMT+1) as I get the impression that the server admins are only able to access it during office hours, which finish somewhat earlier in Russia.
Sadly on thursday evening we lost 26 Normal players all sharing the game the way they prefer to play it at a stroke. Today I was too busy to call it in, hoping (as I foolishly often do) that someone else will.
I would recommend Flying Ass Clowns as a fall back server. It's only visible in the server browser if you enable mods first, but if you were going to log in for an evening's fun, it's worth the minutes it takes to restart Il-2. SAS_Strorebror was kind enough to switch the server over to Normal presets expressly because some people here lobbied for more Normal servers. Its mission format is rather elegant and there's tons of PVE activity on there if it's quiet.
I very much enjoy the time I spend on -DED- Normal, but it's sensible to have a fall back and it will help us stay connected as a player community.

There were 26 people on -DED- Normal yesterday evening when it crashed (after being back up for only a few hours).
I enabled mods* and joined The Flying Ass Clowns as did a couple of other -DED- regulars. As it was, the three of us we had some serious fun. As I said before, there's some real effort gone into mission design here, with separate jobs for fighters, mud-movers and bombers. There's believable ground action taking place round the airfields and everything has a strongly cinematic feel. There's also action for tankers including AI tanks and a space set aside for Flying Circus content.
*This requires an Il-2 restart, but does require you to download anything else, just the mission as you join the server.
It would have been an epic session if we could have gotten the other 23 players there too.
As for when it's quiet, there's tons to do with plenty of ground targets, AI tank units and AI aircraft.
The big setback with the FAC Normal server is that it's invisible from the main server browser (due to being a mods on server). This isn't a criticism of the server, it's just that you can't see it's there unless you have mods on - and with mods on you can't see if any mods free servers are there - which with our low numbers and often casual or time-poor player base is bad news.
I would suggest putting up a Normal presets (and locked server) with directions to FAC that can be viewed from the mods off server browser - either that or respectfully request that Storebror turns off the mods (but on this point I couldn't say how essential they are to the functioning of the server).
